Nutanix NCA Exam - Topic 5 Question 17 Discussion

Actual exam question for Nutanix's NCA exam

Question #: 17
Topic #: 5

User are complaining that web application hosted on a Nutanix cluster are running slow. After reviewing the performance metric, it is determined that the CPU Ready time is high in the cluster.

What entity is impacted by CPU ready time?

AOplog

BNIC

CvDisk

DVM

Show Suggested Answer

Suggested Answer: A

The oplog is a critical component of the Nutanix distributed storage fabric and can be impacted by high CPU Ready time. When the CPU Ready time is high, there can be delays in writing data to the oplog, resulting in slower overall cluster performance. Additionally, high CPU Ready time can also lead to increased write amplification, further reducing I/O performance.

vDisk performance can also suffer, but CPU ready is all about the VM.

I thought NIC would be impacted more in these cases.

Wait, are we sure it's just the VM? Could be other factors too.

Totally agree, high CPU ready means VMs are waiting for CPU resources.

It's definitely the VM that's affected by CPU ready time.

From what I practiced, high CPU Ready time definitely indicates issues with VMs, so I’d go with option D.

I’m a bit confused; could CPU Ready time also relate to the NIC or vDisk somehow? I feel like I need to double-check that.

I think CPU Ready time specifically impacts VMs, especially in a clustered environment like Nutanix. It reminds me of a practice question we did on resource contention.

I remember reading that CPU Ready time affects virtual machines, but I'm not completely sure if it's the only factor involved.

This seems straightforward to me. High CPU ready time means the VMs are waiting to access the CPU, so the entity that is impacted is the VM itself. I'm confident D is the right answer here.

I'm a bit confused on this one. Is the CPU ready time specifically impacting the VM, or could it be affecting something else in the Nutanix cluster like the storage or network? I want to make sure I understand this properly before answering.

Okay, I think I've got this. The question is asking what entity is impacted by the high CPU ready time, and since the VMs are running slow, the logical answer is that the VM is the entity impacted. I'm going with D.

This one seems straightforward. CPU ready time is a measure of how long a virtual machine has to wait to access the CPU, so the entity impacted is the VM.

Hmm, I'm not totally sure about this one. Is it possible the CPU ready time could also impact the virtual disk or network performance? I'll have to think this through carefully.

Hmm, I'm a bit unsure about the difference between the answer choices. I'll need to think through each one carefully to make sure I select the right option.

This is a classic case of the VMs being the MVPs (Most Valuable Procastinators) in the cluster. High CPU ready time means they're just sitting around waiting for their turn to shine.

CPU ready time, eh? Sounds like the VMs are doing their best impression of a traffic jam on the expressway. The VMs are definitely the ones feeling the slowdown.

Hmm, high CPU ready time, huh? Looks like the VMs are waiting in line for their turn on the CPU. I'd say that's the entity that's getting the short end of the stick.

CPU ready time? Sounds like the VMs are doing some heavy lifting, but they're stuck in the waiting room. I'd bet my last dollar it's the VMs that are feeling the pinch.
